We can recover instantly in the event of an emergency, and migrating to a new data center involves minimal downtime
Pros and Cons
  • "The most valuable feature is the ability to recover critical systems, such as public safety, within a few minutes. In addition, the RPO is six seconds of data loss, tops."
  • "I had a couple of questions after deployment, but nothing major, about a couple of ways I could tweak it."

What is our primary use case?

Our primary use case is disaster recovery, as well as data center migration when we went to a new VMware infrastructure platform.

How has it helped my organization?

The first benefit was being able to sleep better at night knowing that we can recover instantly. Because we do public safety, we have some databases that are terabytes in size, and were we to have to recover them using standard backup software, it would take a significant amount of time. With Zerto we can recover instantly in the event of an emergency. 

And when we went to a new data center, we had the ability to do a cross-center migration of the systems, and we found Zerto was much faster. We could migrate 25 to 30 servers and have them up and going in less than five minutes in the new environment, with very minimal downtime.

It has also reduced the number of staff involved in data recovery situations. We find that we really only need one person to manage it. That person was able to write up documentation so that any of the other system administrators can jump in and handle it, because of the ease of use.

What is most valuable?

For me, the most valuable feature is the ability to recover critical systems, such as public safety, within a few minutes. In addition, the RPO is six seconds of data loss, tops.

Also, the ability to adjust the journal is important. If there were a ransomware event and we were not able to recognize that ransomware event for, say, four hours, we could go back, literally per minute, to the previous 24 to 48 hours to have instant recoverability. That, to me, is the big value of the product: to have our systems up with very minimal downtime.

For how long have I used the solution?

We've been using Zerto for three to four years.

What do I think about the stability of the solution?

The stability has been excellent unless there is an issue with something on our end. For example, if a virtual replication appliance exists on a specific host and we take the host offline, Zerto will flash alerts at us, which I love. Zerto is always telling us when there's an issue with recovery. But the application itself has never gone down.

We haven't even noticed any over-utilization across our circuits, with the ability to throttle how much it's using. And once the initial sync is done, it's just kilobytes to keep it in sync. We don't see any downtime from using it. We haven't had a disaster situation recovery yet, but when we do, we're confident because our tests with it are successful.

What do I think about the scalability of the solution?

Scaling has been easy in that we had multiple data centers that we needed to combine into one. It was very easy to create "spokes," where we installed different Zerto appliances in the other data centers and then linked them to the master to migrate them over. From a VPG perspective, we've had to scale out and it's never been a problem.

We have about 250 virtual servers. We had about 100 and we recently purchased another 150 licenses so that we could protect the entire environment. We're in the process of applying those licenses to all of them. We haven't applied all of them yet because we like to categorize which Virtual Protection Groups we want them to be in, so that they spin up at certain times. We like to think that out a little.

How are customer service and support?

Their support has been very good. I haven't had to open very many tickets, but the few times I have, I have gotten a response within an hour or two. The support is good. They handle everything all the way through to completion and then they say, "We'll keep this ticket open in case you have any more issues."

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We used VMware's SRM, which was a great solution; there was nothing wrong with it. But with Zerto, it's like riding a bike. Once I learned it and knew how to do it, I could let it run and do its thing. Maybe a month later I would have to jump in and do something, and the user interface is so easy. I don't have to relearn or remember how it works.

Zerto is quite a bit better when it comes to ease of use, compared to SRM. It's very user-friendly. With SRM, I definitely had to do some learning and read some things. With the VPG, it was almost self-explanatory, such as how to set up VPGs, how to recover things, how to do a failover, and how to do a test. Even as a proof of concept for management, I was able to take a VPG, delete a bunch of files on it, and then recover them from a few minutes prior. It was so user-friendly that even my management was able to watch me do it and understand what was going on.

SRM was just kind of there, in place, and it worked. Zerto is the one that I've really dug into and got my hands dirty with. Once we started utilizing it and realized how quickly we could recover. We realized that it could be used for migrating to a new data center. When we called Zerto we found out that that is a use case people use it for. From a speed perspective, the servers were down for less than five minutes when we migrated them. It was really fast with very little downtime.

How was the initial setup?

The whole process was extremely straightforward. I did a little bit of learning in the Zerto University on how to do a quick deployment. There are not a lot of steps to the quick deployment. After just a few steps we were up and going, almost instantly.

After the installation, it prompts you to log in, and as soon as you log in, it starts telling you what to do. It says, "You need to deploy your virtual replication appliances." And then it says, "Great. Now that you've done that, you're ready to create VPGs." It was almost like the application was literally telling me what to do next.

What about the implementation team?

We deployed it ourselves. I had a couple of questions after deployment, but nothing major, about a couple of ways I could tweak it. But the initial deployment didn't need any technical support. It was that easy to deploy.

Which other solutions did I evaluate?

We looked at a few other solutions. Zerto was the one that really stuck out, especially once we were given a proof of concept.

What other advice do I have?

Definitely try it out. I was able to leap right into it and use it immediately and do a test case within a matter of minutes. I was able to show management the ease of use and the ability to recover, and of course, that makes management happy.

Reduced our downtime on some critical applications
Pros and Cons
  • "I prefer Zerto because it's a little more automated. VMware has more requirements... It's a little more click-and-go versus click-and-monitor..."
  • "Whenever we do a failover, there's a confirmation box that shows up later. It's a little hard to see sometimes... A popup to continue would be a little bit better because then you're not sitting and waiting for something and it's already there."

What is our primary use case?

I've used it for a temporary migration. We had to shut down a data center and we moved some database servers over to a disaster recovery site. We then did the maintenance at the data center and brought them back.

We're using it only for on-prem and we use it to replicate from our onsite data center to a co-location, but there is a fiber connection between the two, so it isn't an internet-based replication.

How has it helped my organization?

In that migration instance we had six terabytes of data that we needed to protect and bring online quickly. We had a replication going and we made the protection group switch and brought the systems back within less than 30 minutes. It reduced our downtime on some critical applications.

If we hadn't used Zerto, we would have had to vMotion them to the other side and that could have taken hours. That could also potentially have been unreliable because there's a timeout period when vMotion works. We used Zerto to be safe.

What is most valuable?

It is pretty simple to use.

What needs improvement?

Whenever we do a failover, there's a confirmation box that shows up later. It's a little hard to see sometimes. We'll do the failover and some preparation activities and then there's a checkbox you need to check to continue and sometimes it's small, in the corner, depending on which screen you're using. A popup to continue would be a little bit better because then you're not sitting and waiting for something and it's already there.

We also had an issue with a misnamed network. They should make that a little more apparent when it's not available on the destination side. We were able to go all the way through with it, but when we did the recovery, it wasn't available. A pre-check to say, "Hey, it's not available. What network do you want to use?" would be helpful.

For how long have I used the solution?

I have been using Zerto for about a month because I'm new with my current company.

What do I think about the stability of the solution?

The stability has been alright. We have failed over quite a number of machines.

We did have an issue with one failover. It didn't fail over completely. You really don't want to have to contact support in those situations, but we had to. It could have been an issue on our side as opposed to something being wrong with the configuration. I don't know what happened, but they got it working.

How are customer service and support?

We had to call support during that migration because one of the settings wasn't correct. I don't know exactly what went wrong, but we had to create a ticket. Zerto got back to us within an hour, so we were really impressed with the support from them. It was really good. They got us taken care of pretty fast and we were back online during the process, within an hour. They were quick to respond after we submitted the ticket and then they got it fixed. There's not really much more they could have done in that situation.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We use VMware-native as well as Zerto. It's all circumstantial, based on sites. Some sites ended up getting an SRM license, so we have kept them instead of wasting licenses. And some sites use Zerto. Maybe down the road we'll pick one of the products, but for now, we use both.

How was the initial setup?

Zerto was already there when I stepped into the picture. I helped initiate some of the disaster recovery processes. Based on what I saw from the outside, it was easy because it was ready for that situation quickly. It was ready in a business day or less, aside from the replication aspect or the data sync from when you first set up the jobs. But the basic setup to get things going was ready within less than a business day.

What was our ROI?

I would think we have seen return on the investment in Zerto because we use it a decent amount of the time. We have reduced the downtime within the last month because of it as well.

Which other solutions did I evaluate?

We've used SRM from VMware. Personally, I prefer Zerto because it's a little more automated. VMware has more requirements and VMware tools get us stuck sometimes. If the VMware tools aren't working on a virtual machine, it won't replicate over as quickly or start up as quickly because it's waiting for that service. You have to do custom settings to avoid that. Zerto doesn't have that requirement. It's a little more click-and-go versus click-and-monitor and then trace back and see what went wrong.

Zerto is also probably faster because SRM waits for VMware tools to come up and say, "Hey, we're here." That's not a requirement that I know of, with Zerto. Maybe it is. I'm a newer user of the product.

What other advice do I have?

In terms of the number of staff involved in data recovery situations, Zerto hasn't really reduced that. My team generally handles those situations and it's the same number of people, regardless of which product we're using.

Zerto worked and did its job and it was easy to use. My team liked it, and the database administrators, who were the customers in that instance where we did the temporary migration, appreciated it.

I would rate it at eight out 10. Sometimes the interface can be a little tricky. If you're using a disaster recovery application, you're in a stressful situation already. Sometimes there are a lot of confirmations you have to go through just to start the Virtual Protection Group, and then it starts and you have to confirm again a few minutes later. You're stressed out. You're talking via chats with a bunch of people and there were times where that prompt was probably sitting there for minutes, which cost money.

More confirmations upfront and removing that second one later on in the process would be good, or a popup, instead of it being a small checkbox in the corner of the screen, is my recommendation.

Which deployment model are you using for this solution?

When a server needs to be moved over in a crisis situation, this solution has been there to help me out
Pros and Cons
  • "It is way faster than just manually moving VMDKs, etc. It saves hours of time and a significant amount of money."
  • "I have had problems with vRAs. When I am trying to restart a host, sometimes the vRAs will hang. I would like it if they wouldn't migrate off or shut themselves down, then I have to manually work with it a lot of the time."

What is our primary use case?

I primarily use it for disaster recovery backup. Also, whenever we need to move things between our different environments, e.g., moving it to different vCenters and Azure, that is primarily done through Zerto

How has it helped my organization?

We are in the process of doing a disaster recovery test soon, and Zerto is at the forefront of that. Zerto is really helping out with this. The bigwigs, who don't know anything about technology, come to us and then we explain Zerto to them. Whenever we simulate failures, Zerto has been able to seamlessly and instantly recover. This really gives our team big brownie points.

What is most valuable?

The most valuable feature is Instant Recovery. Especially when a server needs to be moved over in a crisis situation, Zerto has been there to help me out in a pinch. It is really fast and responsive. It is always there when you need it most.

It is great for reliability. 

What needs improvement?

I have had problems with vRAs. When I am trying to restart a host, sometimes the vRAs will hang. I would like it if they wouldn't migrate off or shut themselves down, then I have to manually work with it a lot of the time.

For how long have I used the solution?

I have been at the company for about six months and using Zerto the whole time.

What do I think about the stability of the solution?

It is pretty stable. The only problem I have is with the vRAs sometimes freezing up. Other than that, it has been pretty stable and reliable. I feel like we can count on it.

What do I think about the scalability of the solution?

It is very scalable. I feel comfortable with it. if we needed to expand in an instant we could.

How are customer service and support?

I have only used our customer support for upgrades, but they have been great and helpful. I would rate them as 10 out of 10.

How would you rate customer service and support?

Positive

What was our ROI?

If I have networking issues on one vCenter, then I can just Zerto it over to another vCenter. This instantly fixes the problem, saving us time and money. In one case, our phone system was down because we were having a network issue at one of the vCenters. So, I just moved the machine over to the other vCenter through Zerto. It came back online, bringing us back up.

It is way faster than just manually moving VMDKs, etc. It saves hours of time and a significant amount of money.

Which other solutions did I evaluate?

I can compare Zerto to Rubrik's instant VM recovery from our backups. Zerto is faster. Since Zerto is instant, it is always watching while Rubrik has to take time and restore everything.

What other advice do I have?

The solution is really good. I am super happy with Zerto.

I would rate Zerto as 10 out of 10. They are great.

It's a set-it-and-forget-it product, so you don't need to go in except to make sure everything runs smoothly
Pros and Cons
  • "It is the backbone of our DR solution for critical databases that hold the data we can't afford to lose. It provided new opportunities to change how we approach disaster recovery."
  • "I wish Zerto had better file restoration capabilities. We have not been able to use that because of the limitations of Zerto's de-duplication technology."

What is our primary use case?

We use Zerto as our primary disaster recovery tool for our most important servers.

How has it helped my organization?

Zerto is tremendously valuable. It is the backbone of our DR solution for critical databases that hold the data we can't afford to lose. It provided new opportunities to change how we approach disaster recovery. 

We realized the benefits quickly, but I don't think it became a staple of our disaster recovery until about a year into our deployment. In the first couple of months, we had some hiccups with upgrades. Once they sorted everything out, it truly became a core solution for us.

It enabled us to transition from data recovery based in a physical data center to the cloud and protect VMs in our environment. Our RPOs also improved tremendously. When we first started, only one other product offered the same RPOs that Zerto provides. However, the other product was problematic, and Zerto has been solid. Compared to other DR solutions, it works quickly to stand up the failed server at another site and bring it nearly into full production. 

We used it to migrate a server, which provided a wonderful recovery time. It worked well. Our RTOs improved tremendously. It reduced downtime in most situations and the time spent on DR testing. A DR test used to run probably 48 hours and involved around four engineers. With Zerto, it runs for about six hours and only requires two engineers.

What is most valuable?

We couldn't find a product that provides the near-zero recovery point that Zerto offers. The closest we could get was another product that had zero data loss. Everything else had a minimum of 15 minutes of replication time, resulting in data loss.

Zerto can also perform test environment restorations that don't affect production. It's also easy to use. It's a set-it-and-forget-it product. Unless you need to make changes to the devices you protect, you don't need to go in except to make sure everything runs smoothly.

What needs improvement?

I wish Zerto had better file restoration capabilities. We have not been able to use that because of the limitations of Zerto's de-duplication technology. When we used the immutable data copies feature, we had some lag in replication times, so we don't use that anymore. When there is big data movement, it tends to cause some lag.

For how long have I used the solution?

We've been using Zerto for about three or four years.

What do I think about the stability of the solution?

With time, it became a highly reliable and stable solution. We were an early adopter, and it had some hiccups initially. I think they've done a great job streamlining it and making it reliable.

How are customer service and support?

The times that I've needed technical support, they've been very good.I would give it an eight.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

Zerto still hasn't replaced all our other backup solutions, but it has replaced two of them. It is leagues above the other products we used in terms of simplicity and reliability. We have another solution to get around Zerto's file restoration and de-duplication issues. We use Veeam Backup and Replication for that. 

How was the initial setup?

Setting up Zerto is straightforward. The documentation was great, and it is intuitive. Integration with VMware is seamless. It's good at running the scripts needed to run in order to work with VMware. We have a 90 percent virtualized environment. 

What's my experience with pricing, setup cost, and licensing?

I think everything can be cheaper. Pricing limited our ability to use Zerto as much as we'd like, but that's not why we haven't adopted it as our primary backup solution.

Which other solutions did I evaluate?

We evaluated Double-Take, Veeam's replication solution, and Azure's Site Recovery. None could match Zerto's RTO and RPO. The only one that got close was Double-Take, but Double-Take was very problematic.

What other advice do I have?

I rate Zerto eight out of ten. There's always room for improvement. It's one of the best solutions for disaster recovery available right now.

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Good support and integration options, and helpful for having a unified DR approach and achieving our RTOs and RPOs
Pros and Cons
  • "The main purpose of this tool is to allow failover between different data centers and different locations. When one site is unavailable, we can start the failover activity and perform the failover task. When a primary location is unavailable, or there is some hardware or logical issue at the primary location, it allows us to resolve the problem. We are able to start services at safe locations. We handle the disaster recovery process, and this is the main function for which we are using it all the time."
  • "I don't have any input for improvement or a critical feature request at this moment. If anything, a lower price is always better."

What is our primary use case?

We use Zerto for disaster recovery (DR) purposes. We needed a tool to provide a quick resolution during a failure or problem and help us achieve our goals related to our service level agreement (SLA). We needed a tool that would help us in providing the availability of lost services within a specific time frame. We wanted to make sure that in case there is a problem and we have to execute the DR procedure, it is quick, easy, and safe. So, the main purpose for going for Zerto is related to meeting the required parameters for RPO and RTO.

We don't use Zerto for backup purposes. It is used only for virtual machines. We also have physical servers, but we have different tools for backup. 

Currently, we are using it for on-premise data centers, but we also do proof of concept tests with public clouds or hybrid clouds.

How has it helped my organization?

It is very good in terms of end-user experience and functionality. The graphical user interface (GUI) is quite simple, and it shows many values related to the status of replication. You can see the current status of a specific application and the health status of infrastructure on the GUI. You can very quickly navigate the application and find very useful information related to the health status of your infrastructure. You can see if the infrastructure is working fine and if there are any bottlenecks or problems that need to be verified by the IT infra department.

It helps us with standardization. It allows us to have a unified DR approach where with one tool, we can meet the DR requirements of different systems with different levels of DR criticality and classification. We have customers for whom the availability of a particular system is crucial for business, and this system requires a very high quality of replication. At the same time, they also have systems that are not as critical. For a unified approach to the DR process, it is better to use the same DR tool for all applications with different levels of criticality. Instead of using different tools for critical and non-critical applications, it is better to use one single tool and have a unified process. Zerto helps us with that.

Different types of integration allow you to provide the tool not only to specialist teams, such as infrastructure teams, but also to the end-users to perform activities like failover, system recovery, and system protection. Service portal integration and automation integration provide a big value in terms of DR activities. You don't have to wait for VMware specialists to perform the DR failover task. You can do it on your own if you have access to the DRaaS portal, for example. DRaaS portal is DR as a service that we have implemented in our own infrastructure, and it is a part of process improvement in our organization.

It has significantly decreased our RTO for failover to the full scope of an application. You can easily measure DR activities for a specific application. If you are responsible not only for your application as an application owner but also need to provide support to many customers at the same time, such a tool is very good. When you are responsible for delivering as per the SLA for RTO to many customers at the same time, it is very helpful because you can perform required activities automatically, and you can also perform them in parallel.

We are very satisfied with the achieved RTOs. We have specific requirements based on the service delivered values and SLA contracts, and by using the tool, we are able to fully meet RTOs for specific applications, a group of applications, or the whole scope of a data center.

During our DR exercises, we try to simulate the worst-case scenario where a complete data center is unreachable, and we are able to achieve the required RTO. Zerto is able to fully meet our needs, and we are able to achieve the required RTO during our normal and yearly DR exercise. We are receiving exactly what we were promised. However, I can't provide metrics or compare it to another tool because we have been using it from the beginning. I don't have the metrics for how much time it would take if we didn't have this tool, but the values that we are receiving during our annual DR exercise are fully satisfactory. So, it is fully sufficient for us.

The time saved in a data recovery situation depends on the specific scenario and the specific system that needs to be recovered. For example, if you have 50 gigabytes built into a machine that needs to be recovered, then with a traditional backup and restore solution, the recovery is very quick and easy. It would take from minutes to an hour depending upon your infrastructure or the bottleneck in your infrastructure. The problem occurs when you have very big systems with 10, 30, or 50 terabytes to be recovered. In such a case, it doesn't matter if it is ransomware or it is an infra failure. Even though the root cause is not the same, the outcome is the same. The fact is that you don't have a working system, and you need to recover the system. Recovering a big system with the traditional approach could take you a week, which is something that businesses do not accept. With a tool like Zerto, I can fail over the system very quickly. During DR exercises, I performed DR activities for systems with many terabytes of data, and it is not a problem to recover that system and failover. I have very good experience with that. During the training or presentation for my customers, I have shown how it works and what are its advantages. One of them is the possibility of a very quick recovery irrespective of the size of the system. The approach is exactly the same irrespective of whether it is an infra issue or a ransomware issue.

What is most valuable?

The main purpose of this tool is to allow failover between different data centers and different locations. When one site is unavailable, we can start the failover activity and perform the failover task. When a primary location is unavailable, or there is some hardware or logical issue at the primary location, it allows us to resolve the problem. We are able to start services at safe locations. We handle the disaster recovery process, and this is the main function for which we are using it all the time.

The second valuable feature is related to integration. If we want to implement any tool in our company, we want to make sure that it is not sandboxed. It shouldn't be completely isolated from other systems, and it should help other systems to receive feedback. To gain advantages of having tools like Zerto on the board, we want to combine our disaster recovery with other processes, such as incident management or change management. We can integrate these processes using different tools, but usually, the best approach is related to API. So, we can integrate different systems and combine them into a big IT platform, which allows us to achieve more features that are normally not available in the tool itself.

Zerto supports different ways to integrate with or get information from the systems. GUI is one of the options, and technologies like PowerShell cmdlets or RESTful APIs are also very good to exchange data for integration or automation purposes.

We also use Zerto for compliance purposes in case we need to provide evidence. When we perform DR exercises and we have some problems with the infrastructure, we need to prove that some actions were taken. It works very well when we perform DR activities and we want to show external auditors the proof and evidence of performed actions.

What needs improvement?

It is very quickly developed, and new features are provided quite often. I don't have any input for improvement or a critical feature request at this moment. If anything, a lower price is always better.

For how long have I used the solution?

I have been using Zerto for six years. 

What do I think about the stability of the solution?

Its stability is very good. Of course, bugs can be found because this is live infrastructure, which is normal. There are new VMware releases, and there are new operating system releases. If there are some problems with applications, we raise cases, and we get the required support in resolving the issue. So, my experience has been very good.

What do I think about the scalability of the solution?

Its scalability is very good. We can use it in on-prem and hybrid cloud environments. It works well with different vendors.

We are using it for different locations. We are using it for on-premise data centers, and we are also using it for all the production systems that we have. Any increase in its usage will depend on the decision of the company. If the decision is to change the platform and integrate with different vendors, we can choose additional features, but at the moment, we are using only the on-premises functionality.

How are customer service and support?

Their support is very good. We have to meet our SLA, and the infrastructure is very sophisticated and demanding. We have had different cases that need investigation and resolution, and we could always count on Zerto's support, which is available 24/7. I don't have any complaints about their support. I would rate them a ten out of ten. If possible, I would even give them eleven.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I have not worked with any other tool previously. This is the only tool I have used. 

How was the initial setup?

It was quite easy to implement and start the execution. There were no problems. It took us about three months to implement it in production.

What about the implementation team?

For implementation, we were using the services directly from Zerto's support teams. In terms of the number of people, there were two people from the DR team and two from the infrastructure team, which included the networking and VMware teams.

In terms of maintenance, every tool requires maintenance, and when you upgrade, there are some bugs or issues that need to be resolved. Currently, for the maintenance of the application for many customers, one person is enough. Based on the number of protected systems and sophisticated infrastructure that we have, it works very well. It is not something that we should complain about.

What's my experience with pricing, setup cost, and licensing?

Its price is reasonable. I have not worked with other tools, but as compared to its competitors such as VMware, its price is lower. So, in my opinion, its price is good.

What other advice do I have?

Based on our experience and the implementations that we have done successfully, it is the right tool for protecting small environments and very big environments. It fits the needs of organizations that require a few functionalities, and it also fits the needs of organizations with a sophisticated environment comprising managed systems, multiple integrations, etc.

Zerto provides near-synchronous replication. So, the RTO is near zero. It is not equal to zero. From my perspective, there are some specific IT areas where synchronous replication is a must, but in most scenarios or use cases, synchronous replication is like a trap because you need to have a single connection between two replication zones or sites, which I would refer to as a single point of failure. If you have storage that is replicated between two sites, in certain scenarios, you won't be able to perform failover activities. If storage is broken on the primary location and you have enabled synchronous replication, the replicated data is also sent to the recovery site. So, you cannot perform failover activities because you now have corrupted data at both sites or data centers. We have chosen this tool to get out of this trap and be able to failover but not to the exact point in time when the issue occurred. I have experience working with such scenarios. For a specific group of systems that require synchronous replication, I can have an additional level of protection by having other DR tools, and at the same time, I can provide replication by using tools like Zerto. So, I can enable two DR solutions on one protected system and resolve the issues related to different scenarios.

In terms of reducing the DR tasks, because I have not used other tools, I can't provide the metrics for increase or decrease in time. However, considering that the tool is implemented for the whole scope of our application, we do not have to wait and spend weeks or months preparing for the DR test. We are prepared all the time for any issue. We also perform the unknown data center DR exercise allowing us to choose the test data center just before the DR exercise. I can very quickly start the recovery operations without a long preparation phase. This is one of the main features of a DR tool that should be taken into account for a company. You should have a tool that you can use at any time. You should ensure and be confident of the fact that it will work and not create any problems during the failover.

DR exercises generally should be performed by customers and application owners. That's because they know best what the issue is and how to provide a solution. It requires synchronization of some tasks and allowing more critical systems to be failed over before the less critical ones. To perform a global DR exercise preparation and execution, very less staff is required. Communicating with customers about the agenda and defining the scope, tasks, schedule, and other things take most of the time, but the execution phase is quick. It can be executed by one operator. It can be done by an infra specialist or an application owner, but ideally, it shouldn't be done by the specialist team. It should be done by application owners because they know the best about the issue.

I would rate Zerto a ten out of ten. It is a very good tool, and we have had very good experience with it. We have no problems with recommending it to others.

Being able to bring a system up in a matter of minutes is the next best thing to having a high-availability cluster
Pros and Cons
  • "It's one of the easiest products out there, as far as managing and using it go. The UI is pretty dead simple."
  • "The only thing we've noticed that needs improvement is the backend cleanup within VMware. There are some little issues there. I would like to see tighter integration with Vmware... orphan data is an issue within VMware. It doesn't clean up properly when you're moving stuff around."

What is our primary use case?

We've got two data centers, and for any of our applications that are not in some kind of a load-balanced or high-availability cluster, we use Zerto to replicate them, to make them as highly available as possible, without building that into the solution. We replicate between 100 and 150 different VMs from our North Carolina data center to our Chicago data center.

How has it helped my organization?

A small example of the way it's made things simpler is that we were building out a new product, and the original recommendation from the vendor when we were deploying that product was to have the application server closest to the end-users and the database server at our main data center in North Carolina. Once it was implemented, we found out that wasn't the case. We used Zerto to fail over the database to the same data center that the application server was in. We were able to do that really quickly and easily, without having to do a whole lot of extra work, such as having to rebuild the database server. That's one example of how we use Zerto, not just in a standard failover scenario. It made the process a lot easier than it would have been had we not had Zerto.

We have also used it when something happened to a configuration or a database file and it had become corrupted. It happened in the evening, after-hours. Rather than getting the backup engineer involved and trying to restore the files from a backup, we used Zerto to grab the file from a couple of hours previous, restored it, and got things back up and running really quickly. It's definitely a time-saver. We were able to handle it ourselves without needing to get anybody else involved.

What is most valuable?

One of the most valuable things about the solution is the ease of use when it comes to failing things over. The ability to easily test your failover capabilities is really nice. We can actually stand up a VM in an isolated environment, validate that the VM is up and running and that it boots properly, and we can do that in a matter of 30 seconds. Being able to show that to upper management, and that it's working the way it should, provides a lot of value.

It's one of the easiest products out there, as far as managing and using it go. The UI is pretty dead simple.

If everything is set up and configured properly, a failover of one or two systems can be done by one person. Nobody has to be involved other than the application owner, to validate everything, once the failover is done. It's a one-man show.

Continuous data protection is what it's supposed to do. Being able to bring a system up within a matter of minutes is the next best thing to having an actual high-availability cluster. If you're not building high availability into a solution itself, Zerto is the next best option. If we're talking about one or two applications or one VPG (Virtual Protected Group) a failover takes under five minutes, from the point of clicking "Start Failover" to the point of validating everything on the application end.

What needs improvement?

The only thing we've noticed that needs improvement is the backend cleanup within VMware. There are some little issues there. I would like to see tighter integration with VMware. From a recoverability standpoint, it's great when using VMware. But what we have noticed is that orphan data is an issue within VMware. It doesn't clean up properly when you're moving stuff around.

For how long have I used the solution?

Our company has been using Zerto for several years. I took over management of it within the last six months, but I've dealt with Zerto in the past as well.

What do I think about the stability of the solution?

We've had no stability issues. We've had to open one or two cases on small issues, but they've been pretty trivial. There haven't been any critical issues with its stability.

What do I think about the scalability of the solution?

It scales really well. Out of 500 VMs, we're using it for about 150 of them. That's probably not a lot compared to other Zerto customers. But as you add more ESX hosts to your environment, you just add new VRAs to the ESX host. There's not too much to have to worry about when you're scaling up.

We utilize it for everything that we don't build in a high-availability cluster. A lot of our stuff is designed as an HA cluster, but anything that is not designed that way is automatically protected by Zerto.

How are customer service and support?

The technical support is as good as, if not better than, most of the technical support that we deal with. Opening tickets is easy. The support portal is easy to use. Depending on the severity—I've never had to open a Sev 1 case—Sev 2 and Sev 3 cases are answered within 24 hours.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We didn't have a previous solution.

How was the initial setup?

I did not do the initial setup of the solution, but the upgrade from version 8.5 to 9.5 was very simple.

Our engineering team members, three systems engineers, are the main users of Zerto. We don't have segregated roles. I'm the point person for Zerto, and the other guys are backups for managing it and doing recoveries. Maintenance only requires one person.

What was our ROI?

We have seen ROI from a time-management standpoint.

Which other solutions did I evaluate?

I don't know if Zerto reduces the number of people that we need to have involved in a recovery scenario, but it definitely simplifies the process compared to using Commvault, which is our backup solution. If it's something that we need recovered from within a day or two, it's much simpler to recover that file with Zerto than it is from a backup solution like Commvault.

Anybody on our engineering team can probably recover a file using Zerto. I'm not so sure that's the case for Commvault. Our backup admin would probably have to get involved if we're doing a recovery from Commvault. Using Zerto, the UI is so much simpler.

There may be a small possibility that we will look at Zerto to replace Commvault whenever we do replace Commvault. That's a possibility, but it hasn't been brought up yet. We do know we are getting rid of Commvault at some point.

I've used other solutions, like Dell Avamar and Veeam. Veeam is definitely pretty easy to use and on par with Zerto. It's 100 times easier to use than Avamar. Ease of use is one of Zerto's strongest points.

What other advice do I have?

Go for it. It's the best-of-breed for high-availability replication solutions. It really is dead simple to use and easy to implement and maintain. It's not one of those solutions that you have to spend hours a day managing. You look at it for five minutes a day and forget about it.

The biggest lesson I've learned from using Zerto is that high availability, having a good replication solution in place, doesn't have to be a big, complicated, scary mess. It can be simple. It doesn't have to be some huge hurdle that you have to overcome.

Simple and stable disaster recovery solution with fast failover
Pros and Cons
  • "Stable disaster recovery solution with a very simple setup and fast failover."
  • "The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that you're only able to replicate one way. Technical support for this product was fantastic, before they were acquired by HP. You're now able to tell that the company is becoming too big, in terms of the support they provide."

What is our primary use case?

Zerto is our primary means of failing over our critical production loads that have a relatively low RPO/RTO. This is our use case for this solution.

What is most valuable?

What we like best about Zerto is its fast failover to another data center. It is simple and it works.

What needs improvement?

The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that we're only able to replicate one way using this solution. Now, we are evaluating the clustering of Zerto with Microsoft clustering, so we can replicate both ways and both data centers, and have the management server in both data centers.

Historically, Zerto has started going into the backup space, and that is when they lost focus on keeping their replication product good. Now, it seems they're finally leaving that backup space, and they're just sticking with replication, so in version 9, they have fixed all of my gripes about the product, e.g. they now support VMware tags, Windows bringing over the time on the target side, etc. All of these little things, they are all correcting, because they're now sticking with the replication product.

For how long have I used the solution?

It's been five years since I started using Zerto.

What do I think about the stability of the solution?

Zerto is a single use case product and it works flawlessly. It is stable.

How are customer service and support?

Technical support for this product was absolutely fantastic, but that was before they were acquired by HP. They are still good, but I can tell the company is becoming too big.

Which solution did I use previously and why did I switch?

We didn't previously use a different solution, as this was the first use case or first requirement that we needed to have under a 24-hour RPO/RTO.

How was the initial setup?

The setup for Zerto was very simple.

What about the implementation team?

We implemented this solution in-house. Implementation only took less than a day to complete. Zerto was ready to use in our environment for a DR (disaster recovery) exercise weeks later.

What was our ROI?

The return on investment from Zerto was immediate. Instead of having legacy DR failover exercises that involved multiple teams and weekends work of activity, now a single user can fail over everything and get reports to prove that it was failed over and the data integrity was all done. As far as people hours and time, the ROI was instant.

What's my experience with pricing, setup cost, and licensing?

Zerto is fairly expensive. We are on a perpetual three-year subscription, but for my less than 300 VMs that we needed this functionality for, it is worth it. I'm not aware of any additional costs beyond the standard fees for this product.

Which other solutions did I evaluate?

We did evaluate Commvault LiveSync, Veeam, and Dell solutions, though I don't even remember what the Dell product was. We did go through RFP. We went with Zerto because it was simple and it worked, and we didn't have to worry about doing anything else.

What other advice do I have?

We're a Commvault and Zerto customer.

We are on Zerto 8.5, and we are evaluating version 9 update 3.

I have no impression on the scalability of this solution, because we haven't really grown yet. We have 300 endpoints and we've always been in that range. I can't tell how Zerto fares if there's more than 300 endpoints.

We have a primary asset owner who uses this solution, who gets feedback from other IT infrastructure teams of whether their servers need to have a low RPO/RTO. That single asset owner will then put those in Zerto. For deployment and maintenance, we have the primary asset owner, then there's a backup person. The primary asset owner does everything, but if the asset owner isn't available, the backup person will help with support roles.

We don't have plans of increasing Zerto usage, as we've always had a relatively static critical VM count of around 300, e.g. we've gone down to 260, we've gone up to 300, but it's always in a range that's close to 300.

My advice to people looking into implementing this product is that if you have less than a 24-hour RPO/RTO and you need it to work in your target location, then there's no other product for it other than Zerto.

My rating for Zerto is a nine out of ten, because nothing is perfect. Nine is the best rating I could give for this solution, but the key takeaway is that it is a single use case product and it does the job.

With a single click, we are up and running at another site
Pros and Cons
  • "For most use cases, the failover time is a handful of minutes, if that. A single user can run the system."
  • "The tech support on my latest issue wasn't so great. I had to figure a lot of stuff out myself. It could be that I had a Level 1 tech who was new or something, but it seemed like the tech was spitballing, which does not help me."

What is our primary use case?

Right now, we use it just for disaster recovery.

How has it helped my organization?

We have always had a centralized data center. Therefore, if we were to lose connectivity or power, then access to county resources would be cut off until that issue is resolved. If there is a hurricane, it would be the same thing. If we lose power, then we would be down until something comes up. With Zerto, I can quickly get us up and running at the disaster recovery site, provided it is still operational.

For most use cases, the failover time is a handful of minutes, if that. A single user can run the system.

Zerto will reduce the number of staff involved in a data recovery situation. As of now, we have been lucky. We have not had to deal with this type of issue. However, it will require less people going forward. So, I can dedicate people to other tasks in a situation like this.

Disaster recovery would initially require four or five people to handle just the server side. This has now been cut down to just one person.

What is most valuable?

It provides great continuous data protection. The RPOs on things are in seconds.

For how long have I used the solution?

We have been using it for two years.

What do I think about the stability of the solution?

We haven't had any issues. It literally just runs. Once you have it set up, you just leave it alone.

What do I think about the scalability of the solution?

As long as I have the resources and licensing, I can keep going from a scalability perspective.

How are customer service and support?

The tech support on my latest issue wasn't so great. I had to figure a lot of stuff out myself. It could be that I had a Level 1 tech who was new or something, but it seemed like the tech was spitballing, which does not help me.

In previous instances, the technical support was great. They were able to get me up and running fairly quickly.

Which solution did I use previously and why did I switch?

We didn't have a solution like this before that allowed for disaster recovery. Everything was restored from backup, then we had to wait. So, if something went south, then we would need to restore from a backup. I saw the Zerto product was literally one button click, then I can failover to a disaster recovery site and keep going. That was amazing during the initial review of the product. It was just easy.

We started looking at how long it would take to restore from a backup. Rebuilding that infrastructure would take hours, if not days, as opposed to having the ability with Zerto to do a single click, then we are up and running at another site.

It is being used in conjunction with our legacy backup solution.

How was the initial setup?

It was actually fairly easy to set up the solution. Installing it, creating the VPGs, and adding the VMs to it was fairly straightforward.

What about the implementation team?

Working with support on the line, we deployed Zerto in a couple hours.

What was our ROI?

It is about $1,000 per VM, so it is pricey. However, the cost and time (the manpower cost) that it would take several members of IT to restore a backup and every individual piece of the virtual environment would easily exceed the pricing cost.

If we had to trigger it, downtime would go down to whatever the RPO is at that time. Right now, our RPO average is between four and 10 seconds. This is a big cost saver for us. Anytime certain systems are down within the organization, money is lost.

What's my experience with pricing, setup cost, and licensing?

The only negative part that I have seen so far has been the cost. It is kind of pricey, but you get what you pay for. Zerto is a lot faster than other solutions and you get enhanced performance.

Which other solutions did I evaluate?

Eventually, we will expand solution use. While there are some competitors in the market, I don't think any of them get to the ease of use and speed that Zerto has. Even Veem has CDP, which is similar, but it is not as fast, user-friendly, or worry-free.

Veeam CDP was still fledgling at the time of our evaluation. It existed, but wasn't that great. It wasn't anywhere near as robust as Zerto. Commvault had something similar as well, but even their solution doesn't do disaster recovery as quickly as Zerto.

It is important that it has both backup and disaster recovery. As I am looking for a backup and recovery solution, I am looking for something that can do everything.

What other advice do I have?

The solution was bought to help with the mitigation of ransomware.

Right now, we are still in a physical data center. We haven't looked at their solution for going to the cloud. That is something which is coming up. Eventually, we will make the switch over. Right now, we are working on a new backup and DR solution. So, that will go hand in hand once we are done with the on-prem.

I would rate Zerto as 10 out of 10 based on the way that the product works.
